Anthurium plant named ‘Rijn200142’

ABSTRACT

A new and distinct cultivar of  Anthurium  plant named ‘Rijn200142’, characterized by its upright and outwardly spreading plant habit; freely clumping growth habit; relatively small, durable and dark green-colored leaves; red-colored spathes with yellow-colored spadices that are positioned above and beyond the foliage on strong and erect scapes; freely flowering habit; and good inflorescence longevity.

Botanical classification/cultivar designation: Anthurium andreanum cultivar Rijn200142.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the name ‘Rijn200142’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in De Lier, The Netherlands. The objective of the program is to create and develop new compact, freely clumping and freely flowering Anthurium cultivars with strong roots, dark green-colored leaves, attractive spathe color and good inflorescence longevity.

The new Anthurium originated from a cross by the Inventor on Aug. 19, 1999 of a proprietary selection of Anthurium andreanum identified as code number 9613, not patented, as the female, or seed, parent with a proprietary selection of Anthurium andreanum identified as code number 9513, not patented, as the male, or pollen, parent. The cultivar Rijn200142 was discovered and selected by the Inventor as a flowering plant within the progeny of the stated cross in a controlled environment in De Lier, The Netherlands in, July, 2001.

Asexual propagation of the new cultivar by meristem culture in a laboratory in Belgium since November, 2001, has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF SUMMARY OF THE INVENTION

The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of the cultivar Rijn200142. These characteristics in combination distinguish ‘Rijn200142’ as a new and distinct cultivar:

-   -   1. Upright and outwardly spreading plant habit.     -   2. Freely clumping growth habit.     -   3. Relatively small, durable and dark green-colored leaves.     -   4. Red and green-colored spathes with yellow-colored spadices         that are positioned above and beyond the foliage on strong and         erect scapes.     -   5. Freely flowering habit.     -   6. Good inflorescence longevity.

Plants of the new Anthurium can be compared to plants of the female parent, the proprietary selection identified as code number 9613. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the selection 9613 in the following characteristics:

-   -   1. Plants of the new Anthurium had thicker leaves than plants of         the selection 9613.     -   2. Plants of the new Anthurium had thicker spathes than plants         of the selection 9613.     -   3. Plants of the new Anthurium and the selection 9613 differed         in spathe coloration as plants of the selection 9613 had solid         red-colored spathes.

Plants of the new Anthurium can be compared to plants of the male parent, the selection 9513. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the selection 9513 primarily in spathe coloration as plants of the selection 9513 had orange-colored spathes.

Plants of the new Anthurium can be compared to plants of the cultivar Red Love, disclosed in U.S. Plant Pat. No. 11,005. In side-by-side comparisons conducted in De Lier, The Netherlands, plants of the new Anthurium differed from plants of the cultivar Red Love in the following characteristics:

-   -   1. Plants of the new Anthurium had thicker leaves than plants of         the cultivar Red Love.     -   2. Plants of the new Anthurium had thicker spathes than plants         of the cultivar Red Love.     -   3. Plants of the new Anthurium and the cultivar Red Love         differed in spathe coloration as plants of the cultivar Red Love         had solid red-colored spathes.
